ACS Workshop (SQL)
Question 1 (Create,Insert)
1.1 CREATE TABLE และ กำหนด id เป็น primary key
CREATE TABLE employees (
id INT,
name TEXT,
salary REAL,
job TEXT,
--INPUT CODE HERE
);
1.2 ใช้คำสั่ง INSERT data เพื่อใส่ข้อมูลเข้าไปใน table employees และ ใส่ข้อมูลของตัวเองลงไปตามตัวอย่าง
INSERT INTO employees (id, name, salary, job) VALUES
(1, 'Lalita Suriya', 25000, 'Developer'),
(2, 'Somsak Somporn', 42500, 'UX/UI Designer'),
(3, 'Siriporn Amporn', 35000, 'Developer'),
(4, 'alita Somsak', 50000, 'UX/UI Designer'),
(5, 'Preecha Kamon', 55000, 'Frontend Developer'),
(6, 'Preecha Kanya', 27500, 'Backend Developer'),
(7, 'Somporn Thaksin', 30000, 'UX/UI Designer'),
(8, 'Sunan Intira', 20000, 'Frontend Developer'),
(9, 'Kanda Ratree', 23500, 'Developer'),
(10, 'Klahan Suchart', 20000, 'Fullstack Developer'),
(11, 'Sukhon Intira', 60000, 'Data scientist'),
(12, 'Wattana Somboon', 30000, 'Data analytics'),
(13, 'Lalita Thaksin', 55000, 'DevOps'),
(14, 'Somchai Malai', 43500, 'Data analytics'),
(15, 'Mali Amporn', 60000, 'Developer'),
(16, 'Pranee Porntip', 25000, 'DevOps'),
(17, ' Somporn Prasert', 35000, 'Web Developer'),
(18, 'Mongkut Arum', 20000, 'Frontend Developer'),
(19, 'Pranee Wattana', 45000, 'Backend Developer');
INSERT INTO employees (id, name, salary, job) VALUES
--ใส่ข้อมูลของตัวเอง ex. (1, 'Teacher', 25000, 'Student')
Question 2 (UPDATE)
ให้ทำการ อัปเดตข้อมูล job จาก DevOps เป็น DevOps Engineer
UPDATE ____ ___ job = 'DevOps Engineer' ____ job = 'DevOps';
SELECT * FROM _____;OUTPUT:
Question 3 (Delete)
จงลบข้อมูล job ทีมีค่าเท่ากับ 'UX/UI Designer'
DELETE FROM ___ WHERE ___ = "UX/UI Designer";
SELECT * FROM ___ where ___ = "UX/UI Designer";OUTPUT:
Question 4 (Select)
Question 4.1 (Where)
ให้แสดงข้อมูลออกมาตามเงื่อนไขดังนี้
SELECT * FROM ____ ____ ____ > 50000 or ____ = 'Developer' order by job ;OUTPUT:
Question 4.2.1 (Order by)
จงแสดงข้อมูลจากน้อยไปมากโดยใช้ salary เป็นเกณฑ์ Hint: ASC
SELECT * FROM ____ ORDER BY ___ ___;OUTPUT:
จงแสดงข้อมูลจากน้อยไปมากโดยใช้ salary เป็นเกณฑ์ Hint: DESC
SELECT * FROM ____ ORDER BY ___ ___;OUTPUT:
Question 4.3 (Like)
ให้แสดงชื่อที่ขึ้นต้นด้วยตัว S%
จงแสดงข้อมูล ทั้งหมดที่มี name ขึ้นต้นด้วยตัว S Hint: S%
SELECT * FROM ___ WHERE ___ LIKE ___ ; OUTPUT:
Question 4.4 (Operator)
ให้แสดงข้อมูลทั้งหมด โดยมีเงื่อนไขว่าเป็นคนที่ salary > 30000 และ job = 'developer'
SELECT * FROM ____ where ____ > 30000 ____ ____ = 'Developer';
Question 5 (debug)
จากข้อมูลข้างต้นพบว่ามี id ซ้ำกันมากกว่า 1 ทำให้ ไม่สามารถรันโค้ดได้ เพราะ มี id ซึ่งเป็น primary key
- import data from csv to sqlite
- comment ที่ บรรทัดที่ 8(primary key (id)) เพื่อที่จะสามารถรันโค้ดได้
CREATE TABLE Salary_Data_Random_Samples (id INT,
Age INT,
Gender TEXT,
Education_Level TEXT,
Job_Title TEXT,
Years_of_Experience TEXT,
Salary INTEGER,
--PRIMARY key (id)
);
INSERT INTO 'Salary_Data_Random_Samples' ('id','Age','Gender','Education_Level','Job_Title','Years_of_Experience','Salary') VALUES
